Answer 1

Answer:

Prokaryotic origin:

The term bioplasts was employed by Altmann for mitochondria which means self—perpetuating units. This view has been supported by many recent workers showing homology between mitochondria and bacteria, (i) First is the localization of enzymes of respiratory chain, which in case of bacteria, are localized in plasma membrane. Plasma membrane may be compared to the inner membrane of mitochondrion.

De novo origin:

There is no evidence that mitochondria arise de novo (afresh), hence this hypothesis has been discarded.i think this is helpful for u
